An automatic probe construction system and the method thereof are provided. The automatic probe construction system includes a data dereference analysis module, a probe selection module, and a probe verification module. The data dereference analysis module dereferences a plurality of target data of an electronic apparatus according to a plurality of pointers, and constructs a plurality of candidate probes. The probe selection module constructs a control flow graph according to the candidate probes and an instruction code of an executable image file, to select via the control flow graph from the candidate probes at least one dedicated probe. The probe verification module searches the executable image file for an instruction code corresponding to the dedicated probe, to verify the dedicated probe. Therefore, the dedicated probe can be constructed automatically, and the number of the dedicated probes is thus limited.

Automatic probe construction system and method thereof

A computer system and a method for tracking information flow are provided. The computer system divides an information flow tracking task into two decoupled tasks executed by two procedures. The first procedure emulates execution of instructions and divides the instructions into code blocks according to an instruction executing sequence. The first procedure translates the instructions of the code blocks into information flow codes and transmits them to the second procedure. The first procedure further translates the instructions into dynamic emulation instructions and executes the dynamic emulation instructions to generate addressing results of the dynamic addressing instructions. The second procedure executes the information flow codes according to the addressing results to emulate the instructions of the code blocks. Moreover, the method also tries to reduce the amount of data transmission between the two procedures when the first procedure executes the emulation task. Therefore, the efficiency of tracking information flow is enhanced.

Decoupled method for tracking information flow and computer system thereof

A method for authenticating a message in a network is provided. The method includes a step of generating, in a sink device, a private key and a public key. The private key includes a plurality of sub-private keys. The method further includes a step of generating, in the sink device, a signature for the message. The signature includes a sub-private key and an authentication path associated with the sub-private key in a hash tree. The hash tree is constructed during the generation of the sub-public keys.
